Bolt Pattern

The Bolt Pattern is a combination of the number of wheel studs followed by the bolt circle. The bolt circle consists of the measurement of the diameter of an imaginary circle drawn through the center of each wheel stud. An example of how bolt pattern is displayed would be something like 8x6.5” or 8x170. 8-lug bolt patterns are found on most ¾ and 1- ton trucks. 5 and 6-lug fitments are most common on compact trucks and half-ton models.

Wheel Diameter Is the distance from one side of the wheel to the other, measured through the center point of the wheel. Wheel diameter is typically the first measurement you will have in mind when selecting a new set of wheels. Most modern full-size trucks come from the factory with 17”-20” wheels, all depending on the trim package and other factory options.


Wheel Width is measured from one bead seat to the other. Wheel width is also another important factor when picking out a wheel. Common factory wheel widths on full size pickups can be as small as 7” and even smaller on dually applications.

Wheel Backspace is measured (in inches) from the wheel hub mounting surface to the inside edge of the wheel. A numerically higher backspace will pull the wheel further into the wheel well, closer to suspension components. A numerically lower backspace pushes the wheel further outside the vehicle, away from suspension components.


Offset is the measurement of the distance in the hub mounting surface to the center line of the wheel.

Negative Offset is when the mounting surface is behind the wheel centerline. As a result, the wheel is pushed out from under the truck. This gives you a wider more aggressive stance with a deep dish” or “deep lip” look.

Zero Offset puts the mounting surface in the centerline of the wheel. A zero offset or something close to it will give you more of a “flush” look.

Positive Offset is when the mounting surface is in front of the center line of the wheel. This moves the wheel and tire into the wheel well. Choosing a wheel with a positive offset will give you a factory-like look and stance.
